  1. 11. Towards Cortex Isomorphic Attractor Neural Networks

    Författare :Christopher Johansson; KTH; []
    Nyckelord :Attractor Neural Networks; Cerebral Cortex; Minicolumns; Hypercolumns; Potts Neural Networks; BCPNN; and Parallel Computers;

    Sammanfattning : In this thesis we model the mammalian cerebral cortex withattractor neural networks and study the parallelimplementations of these models. First, we review the size, structure, and scaling laws ofthe cerebral cortex of five mammals; mouse, rat, cat, macaque,and human. LÄS MER

  3. 12. On the On-line Tools for Treatment of Deterioration in Industrial Processes

    Författare :Christer Karlsson; Erik Dahlquist; Risto Ritala; Mälardalens högskola; []
    Nyckelord :Deterioration; Industrial Processes; Sensors; Process models; Neural networks; Bayesian networks; Data reconciliation; Steam turbines; Boilers; Energy- and Environmental Engineering; energi- och miljöteknik;

    Sammanfattning : For industrial processes high availability and efficiency are important goals in plant operation. This thesis presents studies and development of tools for on-line treatment of process deterioration and model and sensor errors in order to achieve these goals. LÄS MER

  4. 13. Bayesian inference in probabilistic graphical models

    Författare :Felix Leopoldo Rios; Tatjana Pavlenko; Alun Thomas; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Graphical models; Bayesian inference; predictive classification; decomposable graphs; Tillämpad matematik och beräkningsmatematik; Applied and Computational Mathematics;

    Sammanfattning : This thesis consists of four papers studying structure learning and Bayesian inference in probabilistic graphical models for both undirected and directed acyclic graphs (DAGs).Paper A presents a novel algorithm, called the Christmas tree algorithm (CTA), that incrementally construct junction trees for decomposable graphs by adding one node at a time to the underlying graph.

  5. 14. Selfish Dynamic Spectrum Access in Multichannel Wireless Networks : Complete and incomplete information analysis

    Författare :Ali Özyagci; Jens Zander; Alexandre Proutiere; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Game theory; Multichannel random access; Bayesian game; Nash equilibrium Heterogeneous channels; SRA - ICT; SRA - Informations- och kommunikationsteknik;

    Sammanfattning : The increasing popularity and widespread deployment of wireless data systems fuel the increasing demand for more spectrum. On the other hand, various studies measuring spectrum utilization show that there is a huge variation in spectrum utilization at different times and locations. LÄS MER

  7. 15. Advancing Evolutionary Biology: Genomics, Bayesian Statistics, and Machine Learning

    Författare :Tobias Andermann; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; computational biology; bioinformatics; phylogenetics; neural networks; NGS; target capture; Illumina sequencing; fossils; IUCN conservation status; extinction rates;

    Sammanfattning : During the recent decades the field of evolutionary biology has entered the era of big data, which has transformed the field into an increasingly computational discipline. In this thesis I present novel computational method developments, including their application in empirical case studies. LÄS MER
